This next one, I am certian it is ultra modern. I've seen "Cello" stickers on some of them. On ebay, I see these attributed to Murano but I'm suspicious about that. Some are priced at £25 but I can buy new one's for the same price or less

I knew I'd seen these before on a U.K. website - http://www.jazzitupjewellery.com/cat336_1.htm?source=overture Although it doesn't actually say where they were made.Its interesting that yours had a Cello sticker. I've got a large vase with a Cello sticker and haven't been able to find out anything about it. I came to the conclusion that it was most likely Polish.
